After an erase-suspended program operation is com-
plete, the system can once again read array data
within non-suspended sectors. The system deter-
mines the status of the program operation using the
DQ7 or DQ6 status bits, just as in the standard pro-
gram operation. See
page 26
The system may also write the autoselect command
sequence when the device is in the Erase Suspend
mode. The device allows reading autoselect codes
even at addresses within erasing sectors, since the
codes are not stored in the memory array. When the
device exits the autoselect mode, the device reverts to
the Erase Suspend mode, and is ready for another
valid operation. See
on page 21
The system must write the Erase Resume command
(address bits are “don’t care”) to exit the erase sus-
pend mode and continue the sector erase operation.
Further writes of the Resume command are ignored.
Another Erase Suspend command can be written after
the device has resumed erasing.
